Feat : Implement Light/Dark theme toggle button functionality

[rajgharat07]

Describe the feature

• The Light/Dark theme toggle feature allows users to switch between two visual modes: a light theme, which uses brighter colors and a white background, and a dark theme, which uses darker colors and a black or dark background. This feature enhances user experience by accommodating different lighting conditions, reducing eye strain in low-light environments, and providing a customizable look and feel.
